CC   -!- FUNCTION: Protein that can both mediate the addition of adenosine 5'-
CC       monophosphate (AMP) to specific residues of target proteins
CC       (AMPylation), and the removal of the same modification from target
CC       proteins (de-AMPylation), depending on the context (By similarity). The
CC       side chain of Glu-236 determines which of the two opposing activities
CC       (AMPylase or de-AMPylase) will take place (By similarity). Acts as a
CC       key regulator of the unfolded protein response (UPR) by mediating
CC       AMPylation or de-AMPylation of Hsc70-3/BiP. In unstressed cells, acts
CC       as an adenylyltransferase by mediating AMPylation of Hsc70-3/BiP at
CC       'Thr-518', thereby inactivating it. In response to endoplasmic
CC       reticulum stress, acts as a phosphodiesterase by mediating removal of
CC       ATP (de-AMPylation) from Hsc70-3/BiP at 'Thr-518', leading to restore
CC       HSPA5/BiP activity (By similarity). {ECO:0000250|UniProtKB:A0A061I403,

CC   -!- ACTIVITY REGULATION: The side chain of Glu-236 determines which of the
CC       two opposing activities (AMPylase or de-AMPylase) will take place. In
CC       response to endoplasmic reticulum stress, mediates de-AMPylase activity
CC       (By similarity). Adenylyltransferase activity is inhibited by the
CC       inhibitory helix present at the N-terminus: Glu-236 binds ATP and
CC       competes with ATP-binding at Arg-375, thereby preventing
CC       adenylyltransferase activity (By similarity). In unstressed cells,
CC       disengagement of Glu-236 promotes adenylyltransferase activity (By
CC       similarity). Activation dissociates ATP-binding from Glu-236, allowing
CC       ordered binding of the entire ATP moiety with the alpha-phosphate in an
CC       orientation that is productive for accepting an incoming target
CC       hydroxyl side chain (By similarity). {ECO:0000250|UniProtKB:A0A061I403,

CC       pass membrane protein {ECO:0000250|UniProtKB:Q8SWV6}.
CC   -!- DOMAIN: The fido domain mediates the adenylyltransferase activity.
CC       {ECO:0000250|UniProtKB:Q9BVA6}.
CC   -!- SIMILARITY: Belongs to the fic family. {ECO:0000305}.
